Ukutshaja imoto yombane kuya kukhawuleza ngenxa yetekhnoloji entsha, kwaye isenokuba sisiqalo nje.
Uninzi lwetekhnoloji ephucukileyo ephuhliswe yiNASA kwimishini esithubeni ifumene usetyenziso apha eMhlabeni.Eyamva nje kwezi inokuba bubuchule obutsha bokulawula ubushushu, obunokwenza ii-EVs zihlawule ngokukhawuleza ngokuvumela amandla amakhulu okuhambisa ubushushu, kwaye ngaloo ndlela amanqanaba aphezulu okutshaja.

Uninzi lwemisebenzi yendawo yeNASA yexesha elizayo iya kubandakanya iinkqubo ezinzima ekufuneka zigcine amaqondo obushushu athile ukuze asebenze.Iisistim zamandla e-nuclear fission power and vapour compression heat pumps ekulindeleke ukuba zisetyenziselwe ukuxhasa uthumo lweNyanga noMars ziya kufuna izakhono zokuhambisa ubushushu.
Iqela lophando elixhaswa yi-NASA liphuhlisa iteknoloji entsha "engayi kufezekisa i-odolo-ye-magnitude yokuphucula ekugqithiseni ubushushu ukwenzela ukuba ezi nkqubo zikwazi ukugcina amaqondo okushisa afanelekileyo kwindawo, kodwa kuya kwenza ukunciphisa okukhulu kobukhulu kunye nobunzima be-hardware. .”
Ngokuqinisekileyo oko kuvakala ngathi yinto enokuba luncedo kwi-DC enamandla amakhuluizikhululo zokutshaja.
Iqela elikhokelwa nguNjingalwazi weYunivesithi yasePurdue u-Issam Mudawar uye waphuhlisa i-Flow Boiling and Condensation Experiment (FBCE) ukwenzela ukuba izigaba ezimbini zokuhamba kwamanzi kunye nokuvavanya ubushushu buqhutywe kwindawo ye-microgravity kwi-International Space Station.
Njengoko i-NASA icacisa: “I-FBCE's Flow Boiling Module iquka izixhobo ezenza ubushushu ezifakwe ecaleni kwendonga yomjelo wokuhamba apho isisipholisi sinikezelwa sikwimo yolwelo.Njengoko ezi zixhobo zifudumala, ubushushu bolwelo kumjelo buyanda, yaye ekugqibeleni ulwelo olusecaleni kweendonga luqalisa ukubila.Ulwelo olubilayo lubumba amaqamza amancinci kwiindonga ezisuka kwiindonga kwi-frequency ephezulu, rhoqo ukutsala ulwelo ukusuka kummandla ongaphakathi womjelo ukuya kwiindonga zomjelo.Le nkqubo idlulisa ubushushu ngokufanelekileyo ngokuthatha ithuba lobushushu obusezantsi bolwelo kunye notshintsho olulandelayo lwesigaba ukusuka kulwelo ukuya kumphunga.Le nkqubo iphuculwa kakhulu xa ulwelo olunikezelwa kumjelo lukwimo epholileyo (okt kakuhle ngaphantsi kwendawo yokubilisa).Le entshaukubila okupholileyoubuchule bukhokelela kuphuculo olukhulu lokufudumeza ubushushu xa kuthelekiswa nezinye iindlela.
I-FBCE yaziswa kwi-ISS ngo-Agasti ka-2021, kwaye yaqala ukubonelela ngedatha ebilisayo ye-microgravity ekuqaleni kuka-2022.
Kutshanje, iqela likaMudawar lisebenzise imigaqo efundiweyo kwi-FBCE ukuya kwinkqubo yokutshaja ye-EV.Ukusebenzisa le teknoloji intsha, i-dielectric (engaqhubekiyo) i-coolant yamanzi impontshwa ngentambo yokutshaja, apho ibamba ubushushu obuveliswa ngumqhubi ophetheyo ngoku.Ukubilisa ukuhamba okupholileyo kwenze ukuba isixhobo sisuse ukuya kuthi ga kwi-24.22 kW yobushushu.Iqela lithi inkqubo yalo yokutshaja inokubonelela ngoku ukuya kuthi ga kwi-2,400 amps.
Lo myalelo wobukhulu unamandla ngakumbi kune-350 okanye 400 kW eyona CCS yanamhlanje inamandla.iitshajakuba iimoto zabakhweli zingenza.Ukuba inkqubo yokutshaja ephefumlelweyo ye-FBCE inokuboniswa kwisikali sorhwebo, iya kuba kwiklasi enye kunye neNkqubo yokuTshaja ye-Megawatt, engowona mgangatho wokutshaja we-EV onamandla kakhulu okwangoku ophuhlisiwe (esiwaziyo).I-MCS yenzelwe ubuninzi bangoku obuzii-amps ezingama-3,000 ukuya kuthi ga kwi-1,250 V—amandla anokuba yi-3,750 kW (3.75 MW) yamandla aphezulu.Kumboniso kaJuni, itshaja engumzekelo ye-MCS yaphuke ngaphezu kwe-MW enye.
